Benefits of technology

"The present invention provides a portable charger that is easy to carry with small size and can charge different size batteries. The charger includes a charge circuit and a battery compartment with conductors and contacts for charging. The battery compartment can be rotated to accommodate different batteries and is detachably coupled to the charger body. The charger also has a rotational holder for adjusting the size of the battery compartment and a switch for choosing different types of batteries. The charger is small, easy to carry, and can be used for different types of batteries."

Problems solved by technology

However, since the battery compartment is attached to the charger body, conventional battery charger is of large volume, causing inconvenience for carrying and handling.

second embodiment

the battery charger in accordance with the present invention includes two holders 108 that are rotatedly coupled to charge body 10, as shown in FIG. 6. Each of the two holders 108 has a locator 110 and two conductors 102 and two stoppers 112 are arranged on charge body 10. The holders 108 can freely rotate from a horizontal position (0 degree) to a vertical position (90 degrees), adjusting the space to accommodate batteries for charging. For example, at the vertical position, each of the two holders 108 rotates until its locator 110 reaches stopper 112. Then, a large space is provided within battery compartment 20 for receipt of an AA battery 4 for charging, as shown in FIG. 7. Alternatively, at the horizontal position, holders 108 define the space within battery compartment 20 for receipt of an AAA battery 6 for charging, as shown in FIG. 8.

In accordance with another embodiment of the present invention, each of these two holders 108 may be respectively rotated so that one is at hor...

Abstract

The present invention relates to a portable battery charger, which includes a charger body of charge circuit coupled to a power supply and a battery compartment pivotally coupled to the charger body. The battery compartment rotates pivotally around the charger body to provide a fold position at which both battery compartment and charge body form one unit and a charge position at which at least one battery is inserted into the battery compartment for charging. The battery charger in accordance with the present invention shrinks its size to the charger body with a feature of easy carry.

Description

TECHNICAL FIELDThe present invention generally relates to battery charger and, more particularly, to a portable battery charger of small size and easy carry.BACKGROUNDWith rapid development of economy and business, people travel worldwide with portable electronic devices to be driven to operate by battery. Therefore, chargeable battery becomes highly demanded and as a result, battery charger becomes a necessary device in home and travel. A battery charger is generally composed of two parts, a charger body of a charge circuit coupled to an AC power supply and a battery compartment for receipt of a battery to be charged. Conventional chargers have their battery compartments attached to their charger bodies and the battery compartments have fixed sizes to hold particular batteries such as either AA or AAA type batteries.At opposite of the battery compartment, two conductors connected to the charging circuit are arranged to provide contact with a chargeable battery for charging it. A ba...
